Masaki, I'm reading about all these new techniques and am amazed at how things have progressed since I had my daughters (who are now 32 and 28).
It takes a while until your bodies adjust to the sleep deprivation. At least you have a computer and all night TV to keep you company in the wee hours. I would sit and nurse while watching a test pattern! It was hypnotic! :D
Glad to hear Marika is doing so tremendously well!
Hugs to you all!
